Opis:
The damage (in real terms after adjusting for infl ation) caused by extreme weather events globally has increased dramatically over the past few decades. This is a result of an increase in the amplitude and frequency of weather extremes, as well as of human factors causing a widespread increase in levels of exposure and vulnerability. There are a number of reasons to consider that, in many regions of the globe, weather extremes (e.g. heat waves, droughts, forest fi res, intense rainfall, fl oods and landslides) are becoming both yet more extreme and more frequent. Projections for the future based on climate and impact models point to a further strengthening of this trend. There has already been an increase in rainfall intensity in conditions of a warmer climate, and a continuation of this trend is expected, with adverse consequences for fl ood risk. However, the development of fl ood-prone areas and increase in damage potential are often the dominant factors underpinning growing fl ood damage and fl ood risk. In warmer climates, an increased risk of river and fl ash fl ooding caused by heavy rainfall, as well as an increasing risk of coastal fl ooding associated with sea level rise can be expected over large areas. By the same token, a reduction in the risk of snowmelt fl ooding events is projected in the warmer climate. Projections also indicate an increased risk of drought in many areas. The projections for climate change in Poland point to several risks associated with an increase in the frequency, intensity and severity of weather extremes (heat waves, intensive rainfall, fl ooding and landslides, coastal surges, drought during the growing season and winter, strong winds and pathogens associated with warming). Heat waves will become more frequent, more intense and more troublesome for the ageing population of Poland.

Podstawowym zadaniem systemu elektroenergetycznego jest zapewnienie ciągłości i niezawodności dostaw energii elektrycznej. W warunkach realnego niebezpieczeństwa wystąpienia awarii systemowych, do których przyczyn należy zaliczyć czynniki atmosferyczne, techniczne oraz czynniki ludzkie, istnieje ryzyko związane z zagrożeniem bezpieczeństwa systemu elektroenergetycznego. Do najczęstszych przyczyn awarii systemowych należą ekstremalne warunki atmosferyczne, których wpływ na pracę systemu elektroenergetycznego zostanie przeanalizowany w niniejszej pracy. Dla trzech wariantów ekstremalnych warunków atmosferycznych, takich jak osad sadzi, silny wiatr i wysoka temperatura, przedstawiona zostanie zmiana wysokości zwisu na przykładzie przęsła linii 20 kV.
The major task of the power system is to ensure the continuity and reliability of electricity supply. In conditions of real danger of systemic failures, which reasons include atmospheric, technical and human factors, there is a risk related to the threat to the security of the power system. The most common causes of systemic failures include extreme atmospheric conditions, the impact of which on the operation of the power system will be analyzed in this work. For three variants of extreme weather conditions, such as planting sludge, strong wind and high temperature, there will be shown the changes in the overhead line slack on the example of a 20 kV span.

Opis:
Background. Mycotoxins – substances harmful to humans, are ubiquitous in the environment. Mycotoxins are generated primarily by Penicilium, Aspergillus and Fusarium genus fungi. Their presence is associated with the unavoidable presence of mold fungi in the environment. The presently observed adverse climatic changes could negatively affect agriculture, causing erosion and loss of organic matter from soil, promulgation of pests and plant diseases, including those originating from pathogenic molds, and also migration of certain mold species into new regions, ultimately creating more favorable conditions for generation of mycotoxins. Objective. The purpose of this work was to investigate contamination of cereals in Poland with Fusarium and ochratoxin A. Elucidating a correlation between precipitation levels in the individual Provinces and reported levels of the investigated mycotoxins, referring to the generally available meteorological databases, would result in more efficient planning of sampling processes and focusing further preventive actions associated with establishing sampling plans for the following years. Material and methods. Investigations were performed on cereal and cereal product samples taken by the official foodstuffs inspection staff. Some 100 samples were taken annually in the 2009-2012 period (357 samples in total). Tests were performed using high performance liquid chromatography coupled with mass spectrometry (HPLC-MS/MS). Precipitation data were obtained from the Central Office of Statistics, based on data received from the Institute of Meteorology and Water Management. Results. Analysis of the influence of precipitation levels during vegetation period on mycotoxin levels in the investigated foodstuffs was performed by associating each recorded content of deoxynivalenol (n=52, corresponding to 14.6% tested samples), zearalenone (n=30, 8.4%), total T-2 and HT-2 toxins (n=21, 5.9%) and ochratoxin A (n=88, 24.6%) above quantification limit with precipitation levels within the Province from which the sample originated. Deoxynivalenol and zearalenone levels show distinct variability corresponding with variability of precipitation levels, well reflecting the reported higher deoxynivalenol and zearalenone levels observed during the rainy years of 2011-2012. Variability in average ochratoxin A levels was not statistically significant. The relatively higher mycotoxin levels in 2009 may result from the heavy rainfall and flooding of 2007-2008. Dependence between the precipitation levels and number of samples showing levels above quantification limit has been also observed for deoxynivalenol. However, a similar analysis made for zearalenone and ochratoxin A does not point to any significant relationship. No data analysis was possible in reference to total T-2 and HT-2 toxins content due to the insufficient number of results available. However, it should be noted that 21% analyzed samples in 2009 contained T-2 and HT-2 levels above the quantification limit, with average of 8.9 μg/kg, whereas in 2010-2012 only one sample of the 263 tested contained contaminants in quantities above the quantification limit. Conclusions. The model used for forecasting presence of mycotoxins in cereals does not allow its practical application during routine generation of official control and monitoring plans on national scale. Notably, tests performed show that exceeding of maximum contamination levels occurred just incidentally, notwithstanding the adverse weather conditions. Further systematic collection of data on mycotoxin contamination of agricultural crops is required for effective continued investigations.
Wprowadzenie. Mikotoksyny – związki o niepożądanym działaniu dla człowieka są powszechne w środowisku. Są wytwarzane głównie przez grzyby z rodzajów Penicilium, Aspergillus i Fusarium. Ich występowanie jest związane z nieuniknioną obecnością grzybów pleśniowych w środowisku. Niekorzystne zmiany klimatyczne, jakie obecnie są obserwowane, mogą spowodować niekorzystne zmiany w rolnictwie, takie jak erozja i utrata materii organicznej z gleby, rozpowszechnianie się szkodników i chorób roślin, w tym wywołanych przez patogenne pleśnie, jak również migrację niektórych gatunków pleśni na nowe regiony, oraz stworzyć dogodniejsze warunki do wytwarzania mikotoksyn. Cel. Celem pracy było zbadanie zanieczyszczenia toksynami Fusarium i ochratoksyną A zboża w Polsce i stwierdzenie korelacji pomiędzy wielkością opadów na terenie poszczególnych województw a poziomami badanych mikotoksyn, z wykorzystaniem powszechnie dostępnych baz danych meteorologicznych, co pozwoliłoby na wydajniejsze planowanie pobierania próbek oraz skoncentrowanie dalszych działań zapobiegawczych przy tworzeniu planów pobierania próbek na następne lata. Materiały i metody. Materiał do badań stanowiły próbki zboża i produktów zbożowych pobrane przez pracowników urzędowej kontroli żywności. Pobrano po ok. 100 próbek w okresie 2009-2012 (łącznie 357 próbek). Do badań zastosowano metodę wysokosprawnej chromatografii cieczowej sprzężonej z spektrometrią mas (HPLC-MS/MS). Dane dotyczące opadów pochodziły ze strony Głównego Urzędu Statystycznego, gdzie wykorzystano dane Instytutu Meteorologii i Gospodarki Wodnej Wyniki. W celu analizy wpływu poziomu opadów w okresie wegetacji na poziomy mikotoksyn w badanych środkach spożywczych każdej zarejestrowanej zawartości powyżej granicy oznaczalności deoksyniwalenolu (n=52, co odpowiada 14,6% zbadanych próbek), zearalenonu (n=30, 8,4%), sumy toksyn T-2 i HT-2 (n=21, 5,9%) oraz ochratoksyny A n=88, 24,6%) przypisano wartość opadów na terenie danego województwa, z którego pochodziła próbka. W przypadku deoksyniwalenolu i zearalenonu wyraźnie widoczna jest zmienność poziomów tych mikotoksyn, która jest adekwatna do zmiany poziomu opadów, dobrze odzwierciedlając wyższe poziomy deoksyniwalenolu i zearalenonu w deszczowych latach 2009-2010, względem bardziej suchych lat 2011-2012. Zmienność średniego poziomu ochratoksyny A nie jest istotna statystycznie. Relatywnie wyższy poziom mikotoksyn w latach 2009 może wynikać z bardzo deszczowych i powodziowych lat 2007-2008. Dla deoksyniwalenolu współzależność obserwuje się także pomiędzy poziomem opadów, a liczbą próbek powyżej wartości granicy oznaczalności. Jednak podobna analiza dla zearalenonu i ochratoksyny A, nie wskazuje na istotną zależność. Z uwagi na niewystarczającą liczbę wyników, nie była możliwa analiza danych w odniesieniu do sumy toksyn T-2 i HT-2. Należy jednak odnotować, że w 2009 roku 21% zbadanych próbek zawierało poziom toksyn T-2 i HT-2 powyżej granicy oznaczalności, a wartość średnia wyniosła 8,9 μg/kg, w kolejnych latach tj. 2010-2012 zarejestrowano zaledwie jedną próbkę spośród 263 zbadanych zawierającą poziom zanieczyszczenia powyżej granicy oznaczalności. Wnioski. Zastosowany model przewidywania występowania mikotoksyn w zbożach nie pozwala na praktyczne zastosowanie go w podczas rutynowego tworzenia planów urzędowej kontroli i monitoriungu w skali całego kraju. Należy stwierdzić, że mimo niekorzystnych warunków pogodowych, jakie wystąpiły w trakcie realizacji badań, przekroczenia najwyższych dopuszczalnych poziomów zanieczyszczenia pojawiały się incydentalnie.

Opis:
The number of mining operations is increasing in the Canadian North, where extreme weather conditions govern. Currently, many mine development projects are also in progress in this region. These mines’ working atmosphere and employment circumstances are highly different from regular mines. One of the main differences is the special safety issues of the Canadian North. The primary sources of these special issues are: the difficulty of finding skilled employees; high employee turnover rate; insufficient training and certification requirements; delicate employment circumstances affecting the psychological well-being of employees; permafrost; mine inspection challenges; inventory and logistic hardship; and the legislative and regulative necessities corresponding to the particular working environment. This paper aims to set forth specific safety cases in the mines located in the Canadian North. Then, it argues the characteristics of safety organizations and management required to deal with these cases. Furthermore, how the current frameworks can be improved is discussed. Safety issues stemming from cold weather conditions and location remoteness of mines add further challenges to the viability and implementation of projects. The paper underlines that mining operations need certain safety organizations, management approaches, and specific regulations for the mines operated in remote areas and under severe weather conditions.

Opis:
Problematyka zmian klimatu oraz będących konsekwencją tych zmian ekstremalnych zjawisk pogodowych są obecnie tematem wielu badań a także działań rządów w zakresie przeciwdziałania zachodzącym zjawiskom. Obszary wiejskie i produkcja odbywająca się na tych terenach w Polsce uzależniona jest głównie od naturalnych uwarunkowań pogodowych, to powoduje iż w rolnicy ponoszą często duże straty finansowe z powodu występowania ekstremalnych zjawisk pogodowych. Pakiety ubezpieczeniowe oferowane prze firmy są kosztowne, więc rolnicy korzystają z nich cząstkowo albo wcale. W artykule podjęto temat strat finansowych, które miały miejsce w latach 2010-2014 na terenie 60 gmin województwa warmińsko-mazurskiego. W stosunku do każdej gminy zgromadzono 20 geoinformacji opisujących uwarunkowania przestrzenne, środowiskowe oraz ekonomiczne (straty finansowe). Dzięki wykorzystaniu metody regresji kroczącej wstecznej oraz analizy korelacji uzyskano cztery zmienne niezależne wpływające na wielkość powstałych strat. Należą do nich: powierzchnia, na której wystąpiły straty, powierzchnia która jest wykorzystywana rolniczo - z podziałem na grunty orne oraz łąki i pastwiska oraz wskaźnik warunków wodnych. Ten ostatni czynnik mówi o zdolności gleby do akumulacji wody, a więc ma istotne znaczenie w okresach małej ilości wód opadowych. Przeprowadzone badania pogłębiają problematykę związaną z zachodzącymi zmianami klimatycznymi, które na ternach wiejskich Polski są problematyką dopiero poruszaną.
The issue of climate change and as a consequence of these changes in extreme weather events are currently the subject of many studies and actions of governments in dealing with phenomena occurring. Rural areas and production takes place in these areas in Poland depends mainly on natural weather conditions, it causes that the farmers are often large financial losses because of extreme weather. Insurance packages offered by the company are expensive, so farmers use them piecemeal, or not at all. The article about the financial losses that took place in 2010-2014 in the 60 municipalities of the Warmia and Mazur Region. In relation to each municipality collected 20 geo-information describing spatial conditions, environmental and economic (financial losses). By using the method of moving backward regression and correlation analysis were obtained four independent variables affecting the size of the resulting losses. These include: surface on which the loss occurred, the surface of which is used for agriculture - divided on plowed land and meadows and pastures, and the rate of water conditions. Last variable speaks of the capacity of soil to accumulate water, thus is important in times of small amounts of rainwater. The study exacerbate the problems associated with ongoing climate change, which in rural areas Polish issues are very young.

Opis:
The paper is concerned with an application of the climate-weather change process for a critical infrastructure operating area model to identification and prediction of this process for the port oil piping transportation system operating area. For the considered piping operating area, there are distinguished three different climate-weather change processes and their states. Further, there are identified the unknown parameters of those processes, i.e. the probabilities of the climate-weather change processes staying at the initial climate-weather states, the probabilities of the climate-weather change transitions between the climate-weather states and the mean values of the climate-weather change processes' conditional sojourn times at particular states. Finally, there are predicted the main characteristics of the climate-weather change processes at the distinguished operating area.

Opis:
In the current study we use a three-dimensional model with hydrodynamic and spectral wave modules operating in a coupled mode to simulate the response of currents and wind wave fields to winds of 20–25 m/sec offshore of the protective structure of the Saint Petersburg Flood Prevention Facility Complex. The model was calibrated against field data, which allowed us to obtain a tool describing storm situations in the eastern part of the Gulf of Finland with a satisfactory accuracy. The numerical modeling showed that the protective dam did not have a noticeable effect on the levels of stormsurge, significantwave height, or current speed in areas seaward of the dam. The increase in erosion processes on the southern shore of the easternmost part of the Gulf of Finland in recent past has most probably been related to other factors. We found that if a west or south-west wind of at least 25 m/s blows over the Baltic Sea for at least 16 hours, the level of storm surges seaward of the dam may reach 3 or more meters. An artificial strengthening of the coastline and the creation of shore protection structures are recommended.

Opis:
New shipping routes are emerging as a result of iceberg melting in polar regions, allowing for more efficient transport of people and goods. Opening of the Northwest Passage, the maritime route connecting Pacific Ocean with Atlantic Ocean through Arctic region, is considered such a development. The increasing transport exploitation of the Northwest Passage requires the quality assessment of maritime navigation aids for compliance with the established requirements. Here we contribute to the subject with addressing the polar commercial-grade GPS positioning performance in the Northwest Passage in the extreme positioning environment conditions during the massive 2003 space weather storm, a space weather event similar to the Carrington Storm of 1859, the largest space weather event recorded. The GPS positioning environment in the Northwest Passage during the Carrington-like storm in 2003 was reconstructed through the GNSS SDR receiver-post processing of the experimental GPS observations. The raw GPS dual-frequency pseudoranges and navigation messages were collected at the International GNSS Service (IGS) reference station at Ulukhaktok, Victoria Island, Canada. Pseudorange processing and GPS position estimation were performed in three scenarios of pre-mitigation of the ionospheric effects, known as the single major contributor GPS positioning error: (i) no corrections applied, (ii) Klobuchar-based corrected GPS positioning, and (iii) dual-frequency corrected GPS positioning. Resulting GPS positioning error vectors were derived as positioning error residuals from the known reference station position. Statistical properties of the northing, easting, and vertical components of the GPS positioning error vector were analyzed with a software developed in the R environment for statistical computing to select suitable methods for the GPS positioning error prediction model development. The analysis also identified the most suitable theoretical fit for experimental statistical distributions to assist the model development. Finally, two competitive GPS positioning error prediction models were developed, based on the exponential smoothing (reference) and the generalized regression neural networks (GRNN) (alternative) methods. Their properties were assessed to recommend their use as mitigation methods for adverse massive space weather effects in polar regions.
